Research on intercultural interactions in higher education focuses on measuring student attitudes and degrees of cosmopolitanism, but there is little theoretically and empirically informed effort to understand 1) the nature of these campus interactions as ordinary, embodied, and routine, and 2) the cultural and social impact of campus intercultural interactions. Based on a qualitative study of ethnically diverse, newer migrant university students' experiences in Australia, our research examines ways intercultural interactions occur in everyday routines of higher education and how they reinforce ethnically-based relations of power. We employ and revise the concept "convivialities" -- the everyday, routine, and embodied nature of intercultural interactions that are not directly about ethnicity or ethnic difference -- to offer a nuanced perspective on everyday campus interculturality. We argue ordinary cross-cultural campus interactions can reinforce relations of dominance and subordinance through constituting symbolic boundaries for belonging.
